What is the equation of the line that passes through the point (5, -2) and has a
slope of -2/5
Answer:
y=-2/5x
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-2/5(x-5)
y+2=-2/5(x-5)
y=-2/5x+10/5-2
y=-2/5x+2-2
y=-2/5x

A line with a slope of 1/3 passes through the point (-3, -1). What is its, equation in
slope-intercept form?
Answer:
y = 1/3x
Step-by-step explanation:
y = 1/3x + b
-1 = 1/3(-3) + b
-1 = -1 + b
0 = b
y = 1/3x

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find each probability
Complete question is;
Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.
Answer:
0.93
Step-by-step explanation:
We are given;
Mean; μ = 200
Standard deviation; σ = 12
Random value; x¯ = 218
Z-score formula is;
z = (x¯ - μ)/σ
z = (218 - 200)/12
z = 18/12
z = 1.5
From z-table, attached, probability = 0.93
In a quiz contest, Mary answers 90% of the questions correctly without any additional clues from the quiz coordinator. The randomly generated numbers below simulate this situation.
The numbers 0 to 8 represent questions answered correctly without additional clues, and the number 9 represents questions that needed additional clues.
44 51 99 66 23
68 72 20 20 59
50 89 39 36 20
90 13 51 47 92
49 20 89 10 13
52 82 52 52 99
28 10 33 35 73
40 44 30 95 22
99 10 55 10 35
36 78 92 37 96
The estimated probability that it would take at least three questions for Mary to need additional clues is (_____)
The estimated probability that Mary needed additional clues to answer two consecutive questions is (_____)
To solve this problem, we should note that there are:
total questions = 100
questions answered correctly = 90
questions that needed additional clues = 10
1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:
Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)
Probability = (90/100)*(89/99)*(10/98)
Probability = 0.08256 = 8.26%
2. The second question finds for the probability that two consecutive needs additional clue, therefore:
Probability = (question 1 needed clue) * (question 2 needed clue)
Probability = (10/100)*(9/99)
Probability = 9.1*10^-3 = 0.91%
Answer:
1. The estimated probability that it would take at least three questions for Mary to need additional clues is 0.24
2. The estimated probability that Mary needed additional clues to answer two consecutive questions is 0.06

A triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?
I'll give brainlist!! Pls help
Answer:
Length of the base of the triangle = 19.37 inch (Approx.)
Step-by-step explanation:
Given:
Area of given triangle = 230.56 square inches
Height of the triangle = 23.8 inches
Find:
Length of the base of the triangle
Computation:
Area of triangle = (1/2)(b)(h)
Area of given triangle = (1/2)(Length of the base of the triangle)(Height of the triangle)
230.56 = (1/2)(Length of the base of the triangle)(23.8)
461.12 = (Length of the base of the triangle)(23.8)
(Length of the base of the triangle)(23.8) = 461.12
Length of the base of the triangle = 19.37 inch (Approx.)
an expression that is equivalent to 60x+28y.
Answer:
Step-by-step explanation:
The trick here is to identify the greatest common factor of 60 and 28. 4 is such a factor. We can therefore rewrite 60x + 28y as
4(15x + 7)
There are other possible answers.
600x + 280y

Find x. Round to the nearest tenth and only type the number for your
answer.
25
X
16
22
Answer:
10.7
Step-by-step explanation:
To find x we have to basically do pythagoream theorem twice. Both the traingles share the same long side. The find the long side of the top traingle do, [tex]a^{2} +16^{2} =25^{2}[/tex], and we find the long side to be [tex]\sqrt{369}[/tex]. Using this we now plug it into the pythagoream theorem for the bottom triangle. [tex]\sqrt{369} ^{2} +x^{2} =22^{2}[/tex], and doing this out we find that x=[tex]\sqrt{115}[/tex] or about 10.7.
Find the shaded angle
Answer:
332°
Step-by-step explanation:
Given is an isosceles triangle,
Measures of base angles of an isosceles triangle are equal.
Therefore,
Measure of central angle
= 180° - ( 76° + 76°)
= 180° - 152°
= 28°
Measure of shaded angle
= 360° - 28°
= 332°

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Answer:
x = 59
Step-by-step explanation:
combine all four angle measure expressions and set equal to 360°, then solve
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
6x = 354
x = 59
